I'm not so sure that the 700kbps estimate is accurate. Lighting has such a huge impact on low res video such as the iPads vga camera that it could realistically cost a little more than 1mbps.

With that said, I actually don't know anyone who uses Facetime. In my personal and professional circles, it's really served as little more than an idle curiosity. But then, we're also not kids. I'm sure the teenagers would use an untethered FaceTime as much as they use any other form of communication.

Can you imagine having to get dressed for a phone call simply because your phone call is expected to have video? Video calling sounds like a nightmare to me.

I think it vastly understates Apple's power to say it has no control over how its devices are used on cellular networks. I also think it oversimplifies to say Apple plans to eliminate cellular companies. Apple will always need some form of wireless network access and I don't see them building out or buying it. Yes, they are gradually marginalizing the cellular carriers (as well as broadband carriers) to being little more than dumb data pipes, but they still need the pipes.

The cellular companies mandate no Facetime on their cellular networks. Apple has no control over this. Facetime is part of a gradual plan by Apple to eliminate cellular companies altogether. The cellular companies are too stupid to realize this.

Our latest survey shows growing demand, fixed budgets, and good reason why resellers and vendors must fight to remain relevant. One thing's for sure: The data center is poised for a wild ride, and no one wants to be left behind.
